Structural Diagram of an Aerospace Cognitive Radar for the Earth Remote Sensing

Using the concept of cognitive radar composition and the results of statistical synthesis of algorithms for nonlinear filtering of radar images a block diagram of a cognitive radar for earth remote sensing systems is proposed. The development is based on the assumption that the airborne radar receives signals from an antenna array and implements complex analog and digital signal processing. Taking into account the current state of development of analog-digital processors it is proposed to implement part of the signal processing in analog form at a high frequency and to perform the final filtering after the detection of complex amplitudes in digital form. All components of the block diagram are considered and the logic of their interaction is determined for the implementation of optimal algorithms of radar imaging.
